Cables installed using directional boring equipment must be what?

When cables are installed using directional boring equipment, it is critical that they are approved for this specific method of installation. The use of directional boring can present unique challenges and considerations, including the potential for damage to existing underground utilities and ensuring the proper depth and placement of the cables. Approval for this purpose typically comes from relevant industry standards or regulatory bodies, ensuring that the materials and installation techniques meet safety and performance requirements. This approval is vital to ensure that the cables can withstand environmental factors and provide reliable service without risk of failure due to inappropriate installation methods. Additionally, with the proper approval, the installation adheres to the National Electrical Code standards, ensuring compliance and safety for the entire system.
